OE-Style Coolant Hose for BMW Cooling Systems
Rein CHE0500 is an OE quality engine coolant hose built for European cooling systems that use a branched hose layout and thermoplastic quick connect fittings. It is a direct replacement for the original hose assembly on select BMW 550i and BMW 650i models, helping restore proper coolant routing at the expansion tank and radiator connection.
- Direct OE-style replacement for the original hose assembly
- Branched EPDM hose construction with one quick connect fitting
- Reduces installation time by eliminating hose cutting and refitting
- Helps prevent leaks caused by reusing old quick connectors and O-rings
- Resistant to heat, salt, road debris, oil, and other contaminants
- Built to SAE J20R4D1 standards
Fitment and Application Details
Compatible with 2006-2010 BMW 550i and 2006-2010 BMW 650i in the expansion tank (upper) to radiator position. This Rein CHE0500 coolant hose follows the original size and branch shape called for by the OE design, making it a practical replacement for BMW cooling system service on these applications.
The hose measures 22.83 inches centerline length and uses EPDM material with black finish. End dimensions are sized for the specified BMW application, and the assembly includes one branched section with one thermoplastic quick connect fitting. This part cross-references Genuine 17127534917 for the same application.
Common Problems This Hose Can Address
- Coolant leaks at the upper expansion tank to radiator hose connection
- Cracked or aged hose material from heat cycling
- Damaged quick connect fittings or worn O-rings
- Poor fitment from trimming or adapting a non-OE hose
- Cooling system service delays caused by mismatched hose geometry
Installation Notes and Tips
Verify the vehicle’s cooling system routing before installation and compare the original hose shape, branch layout, and connector style to the replacement part. Because this hose is application-specific, no cutting, refitting, or adjusting should be required when installed on the listed BMW 550i and BMW 650i models. Inspect mating surfaces and replace worn seals as needed during cooling system repair.
Quality Assurance
Rein Automotive OE quality hoses are engineered as direct replacements for original European vehicle hose assemblies. CHE0500 is manufactured to meet SAE J20R4D1 requirements and uses materials selected for resistance to common underhood and road contaminants.
